Ok dude... I'm going to go back and time and tell 15 year old me what to do. You can come and listen if you want.
"First off, let's not rush shit. You always rush shit, so you need to play it cool. Don't say date.. even if it's a date, don't say date. You asked two girls you liked as friends to go to see a movie you wanted, and one got mad you asked the other one first because she thought it was a date. So you gotta be cool.
"So basically say "want to go to the comic book store?" She likes comics she's going to say yes. Heck don't specify a specific time, so when she asks "When?" you know she's interested, work out a time. Even if she asks "like a date" say "what ever" with a smile, she'll think it's cute. Play it cool dude!
"Second do a little research, find some place to eat that's cool. If it goes cool at the comic store, suggest going to grab a bite. Don't choose anything too pricy, casual just two friends chilling out. If she thinks it's a date, it'll work, if not it's just a hang out. Great. Then play it by ear. She might suggest "What do you want to do?" She might just want to go home and even if she doesn't want to eat that's not the worst thing.
"Now dude, I've given you the plan. Let me tell you the other side. You're a fucking idiot, you're going to flub that, but don't freak out. If you say something stupid it's not the worst thing in the world. You're a nerd, but if she's the one for you, she'll like that about you. Just don't rush shit... You got this.
"Good luck Young Kinglink" ( Spoiler, never worked, didn't find my first girlfriend until I was 24... ehhh now married and happy so you get there eventually ). And good luck Chris, but take it easy my friend, and don't push the date aspect too hard unless she's given you signs, and I'm guessing she hasn't... yet.
Others are saying make it clear it's a date, but if you do that, it's binary. She wants to date you and says yes, or she doesn't (and that might hurt your friendship)... she probably doesn't know you well enough to date you yet otherwise you'd know for sure if this was a good idea.
Oh but to answer your question. For the right girl? A comic store date would be perfect, especially if you know she likes comics.
